Treatment of leprous neuritis by neurolysis combined with perineural corticosteroid injection.

A study on leprous neuritis, involving the ulnar nerve, was carried out on 39 patients. The evaluation of nerve function was done before and after treatment by a score chart. Patients were divided into two groups. Group A (21 patients) was subjected to neurolysis only, and group B (18 patients) were given the combined treatment of neurolysis and perineural corticosteroid injection at the same time as neurolysis and subsequently at the end of the second and third weeks. In group B, 83.3% of patients showed 10% or more increase in the posttreatment score in comparison with 57.1% in group A. Improvement was more marked in paucibacillary cases and when the duration of nerve involvement was less than 3 months. Patients with short segments of nerve involvement with minimal thickening had better recovery. This procedure was observed to be simple, easy and well accepted by the patients, with a marked beneficial effect.
